I 'he Schedule referred to in the'se Letters Patent and making part -ofthe'same.

To ail '1v/wm it may conce/rn:

.Be it-known that I, Ennis H. Monats, of Canton',-

in the county of Stark and Stateof Ohio, haveinf' vented a new andvaluable Improvement in'Molding- Planes; and I do hereby declare thatthe following is a'full, clear, and exact descriptionl oftheconstruction andoperation of the same,".reference being had totheannexed drawing making a part of this specification and tothe lettersand figures of reference marked thereon. K

Figure lfof the drawing is a. top view of my plane;

Figure 2 is a side elevation, with the side plate removed; I

Figure 3 is a ,vertical transverse section;

Figure 4 is a bottom view; and

Figures 5, l6, and 7 are details.

My invention 'has relation to an improvement in planes; and y vItconsists in providing a plane-stock with an adjustable face, capable ofbeing molded or shaped to suit a plow-bit of any form; also, inattaching to the plane-stock an adjustable extension-gauge, designed toenable the bit to he run at any desired distance from the edge of aboardor panel, as hereinafter described. f

The letter A oi'v the drawing designates my plane? stock, which may besimilar in itsr external form to the ordinary plane-stocks in commonuse. The under side of the stock is channeled or excavated'from side toside to receive the thin vertical sections which constitute theadjustable face of the stock.

B B represent elongated recesses or ways extending up into the body ofthe plane-stock, from the channel at thehase, at an angle of forty-livedegrees, or corresponding to the angle of the bit. These re` cessesserve to receive the offsets from the face-sections, presently to hedescribed. Usually I make one of these recesses in front of the throatofthe plane, andtwo in rear thereof.

C designates the adjustable face of my plane-stock.

' This is composed of two sets of thin vertical strips d, running in thedirection of the length of the planestock. One set of these strips issituated in front yoi the bit and the other is placed Ain rear,following the bit.

Each strip of the first set is provided with an offset or guiding-arm,e, which' extends upward and backward at an angleof forty-live degrees,or parallel to the bit, into the recess B.

Each stem c is provided with a projection, 7l., at its upper forwardcorner, which is designed to engage with a stop, k, in the wall of therecess. The arm e is arranged to slide up and down in its recess, thedis` tance to which it can descend being regulated by the 'position ofthe stop it and the projection h.

' Each strip of the second or rear set is provided with two guiding-armsf fg-extending upward and rearward, parallel to the arm of the strip-infront ofthe y bit, which immediately precedes it.

The forward arm f of the rear strip is Without a stop, and slides in arecess formed in the rear wall or the throatof the stock` The rear arm fis similar to the arme ofthe for ward strip, being Vprovided with'aprojection, and arrangedto engage .with a stop in the wall of its recesswhich limits the descent of the strip. These stops-k are placed inthe-recesses in such a position that they will allow the strips todescend as far as the lowest point of any one of-the ordinary plow-bitsin use.

These strips'or sections d are usually made thin, in order that they mayvconform as closely as possible to the configuration of the edge of thebit. The faceedge of each strip is'transversely rounded, or beveled oneach side.

D' D represent set-screws, passing through the walll ofthe plane-stock,and serving to secure the strips in their relative position to eachother and to the 'oit after they have been properly adjusted and moldedin form.

Elrepresents my bit, whichis provided with a means of shaping theadjustable face of the stock to suit its cutting-edge.

This consists of a notch or indentation, c, formed in its .upper edge,and correspondingprecisely in shape with the edge ofv thebit, with theexception that the general curve' or prolile is reversed and flatter.

The face-sections' having been adjusted out to ill vthe mold theset-screws are tightened, and the Vstrips thereby rigidly secured inposition. f .The bit and wedge are now inserted in the throat oftheplane-stock, and, having been properly adjusted, the too'l ,i's readyfor operation. This stock, with its adjustable face, may he used 'with astationary gauge, but usuallyI prefer to attach to it my extensiomgauge,as follows: j

At the base of the exterior wall of the stock, on the left or innerside, is formed a projecting ledge, G, which extends usually the entirelength ofthe stock.

At the forward end a circular projection is raised, which serves as abearing for the inner end of the extension-bar H.

A slot, l, traverses longitudinally the rear portion ofthe ledge G.

The underside of the ledge G is recessed atv-c, on each side of the slotl,to receive the ilanches of the nut n.

Krepresents a clamp-screw, by means of which the inner end .of theextension-bar H' ispivoted tothe ledge G. The end of this clamp-screwpasses through the slot l, and, engaging with the square nut n, servesto x thebar H in any desired position.

The bars H andH cross'each other, and are pivoted together at abouttheir middle portions by the pivot a". The outer end of the bar H isbent downward in order to bring it on a level with the outer end of thebar H. y

Z represents the movable gauge-bar. The upper and inner corner of thisbar is recessed at s to receive the ledge G, thus permitting 'the facez' ofthe gauge to be brought up close to the bit, when desirable.

The outer end of the bar 'H' is pivoted to the forward end of thegauge-bar Z.

The 'rear end of the gauge-bar Zs slotted at Z' to receive aclamp-screw, K'whioh' operates, in conjunction with a nut, n', to securethe outer end ofthe bar H at any point of the slot.

The distance to which the gauge can be extended from the bit isregulated by the length of the Acrossbars H'H' and the length of theslots l l'. The gaugebar, when adjusted at the proper distance from thebit, can be rigidly fixed in that position by means of the clamp-screwsK K'.

- A plane constructed in this manner is designed to snbserve purposes ofgreat importance to cabinetmakers and carpenters. To journeymenespecially it will prove a great convenience in the saving that willensue in transportation, one 'stock being sucient for all the bits thatthey may employ. Carpenters, even of small means, can execute a greatvariety of moldings,

limited only by the number of diierent bits which theyl may possess. 4

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A plane-stock, having yan adjustable face, capaf 'ble of being variedin form to suit bits having differently-shaped cutting-edges,substantially as specified,

2. Theoombination, with a plane-stock provided with/a'slotted ledge, G,ofthe slotted gauge Z, cross-` extension arms H H', ,and clamps lK K,substantially as specified.

3. The combination, with a plane-stock having an adjustable face, of abit, provided with 4a forming indentation, substantially as specified.

In testimony that I claim the above I have hereunto subscxibed my namein the presence of two witnesses. l
